Tech News:

“Garmin down — Latest outage updates as cyberattack confirmed and recovery begins”:

See the TechRadar article by Gareth Beavis 29 July 2020.

Even though the above link worked in English a few days ago, it now seems to switch to the Spanish version with the headline:

"Garmin confirma el secuestro de sus servidores: qué ha pasado con tus datos y qué puedes hacer."

No amount of clicking on the "ES(US) Edition" icon where they offer the "Australia Edition" seems to make any difference!

Our apologies — Ed.

Garmin has confirmed a massive cyberattack to its online platforms

Update: 7/28: Garmin has said it was the victim of a "cyberattack", but hasn't confirmed whether ransomware was involved. Sources speaking to news sites have said Garmin didn't make a direct payment to its attackers, suggesting that the company was able to recover its data from backups.

There's no indication that user data was compromised, and the company is working to resume regular services over the next few days.

Garmin has confirmed that the outage it has been suffering since July 23 was due to a cyberattack and that it will be resuming standard functionality soon.

While it was initially dubbed a simple maintenance window, the length of time users were unable to upload runs and workouts, or access things like aviation databases and marine navigation showed that this was a much larger issue.

Garmin's full statement is below:

"Garmin...today announced it was the victim of a cyberattack that encrypted some of our systems on July 23, 2020. As a result, many of our online services were interrupted, including website functions, customer support, customer-facing applications, and company communications."

"We immediately began to assess the nature of the attack and started remediation. We do not indicate that any customer data, including payment information from Garmin Pay, was accessed, lost or stolen."

"Additionally, the functionality of Garmin products was not affected, other than the ability to access online services."

"Affected systems are being restored, and we expect to return to normal operation over the next few days. We do not expect any material impact on our operations or financial results because of this outage."

"As our affected systems are restored, we expect some delays as the backlog of information is being processed. We are grateful for our customers' patience and understanding during this incident and look forward to continuing to provide exceptional customer service and support that has been our hallmark and tradition."

How did this happen?

Initially, Garmin users noticed an extended maintenance period where they were unable to access critical services. Then a tweet confirmed the brand was "experiencing an outage that affects Garmin Connect, and as a result, the Garmin Connect website and mobile app are down at this time".

Rumours began to quickly emerge that Garmin was subject to a massive ransomware attack that had meant it needed to pull its entire platform offline.

TechRadar spoke to the brand after 48 hours of the outage and got a statement to confirm the entirety of its operations were not functioning:

"Garmin is currently experiencing an outage that affects Garmin services including Garmin Connect and Garmin Pilot. As a result of the outage, some features and services across these platforms are unavailable to customers. Additionally, our product support call centres are affected by the outage, and as a result, we are currently unable to receive any calls, emails or online chats."

"We are working to restore our systems as quickly as possible and apologize for the inconvenience. Additional updates will be provided as they become available."

The brand then directed TechRadar to a short Q&A on how Garmin Connect's outage hasn't affected user data — with the primary response to user data being impacted, offering the most solace to users:

"Garmin does not indicate that this outage has affected your data, including activity, payment or other personal information."

On Monday, July 27, after four days of issues for Garmin Connect and its associated services, syncing and access to databases began to return, and the fitness brand admitted that it had been subject to a significant cyberattack.

What's happening?

It's interesting to note the way Garmin is describing the attack, saying it was "the victim of a cyberattack that encrypted some of our systems".

That seems likely to be ransomware. But the brand has shied away from confirming a ransom was demanded to unlock its users' data and access to databases.

However, multiple outlets spoke to sources claiming direct knowledge of the matter, or Garmin employees. They all explained that a hefty ransom was being demanded to unlock large portions of the system and that emergency measures had been implemented to protect Garmin's platforms.

“Intel forced to delay the introduction of 7nm chips by at least a year”:

See the iTWire article by Sam Varghese Saturday, 25 July 2020 05:51.

Intel will be forced to delay the introduction of 7nm CPUs. The company told investors on Friday that it would have to push back the schedule for producing the most advanced semiconductors by six months as it has no economically viable way to build them at the moment.

During the announcement of its second-quarter results, Intel said: "The company's 7nm-based CPU product timing is shifting approximately six months relative to prior expectations. The primary driver is the yield of Intel's 7nm process, which, based on recent data, is now trending approximately 12 months behind the company's internal target."

This delay would mean that it could be 2023 by the time Intel starts producing 7nm-based CPUs. Only two companies — Samsung and Taiwan Semiconductor Manufacturing Company — provide them at the moment. TSMC is looking at starting the production of 5nm-based CPUs next year.

Intel has dominated the processor sector for decades but is now beginning to feel pressure from AMD. The latter is already using 7nm-based CPUs, and by the time Intel catches up, AMD may already have moved to 5nm-based Ryzen 6000 processors based on Zen 4 architecture.

The disclosure came on the day that Intel announced its results for the second quarter, with chief executive Bob Swan saying the firm had identified a "defect mode" in its 7nm production process that led to degradation in yields.

Swan said Intel's data centre GPU design, "Ponte Vecchio", would now be released in late 2021 or early 2022 using external and internal process technologies combined with Intel's packaging technologies.

Intel has revealed its long-awaited graphics processing unit (GPU) architecture, which would be the heart of graphics chips designed to handle substantial data and artificial intelligence loads in data centres.

"We now expect to see initial production shipments of our first Intel-based 7nm product, a client CPU in late 2022 or early 2023," he said. "We are also focused on maintaining an annual cadence of significant product improvements independent of our process roadmap, including the holiday refresh window of 2022."

"Besides, we expect to see initial production shipments of our first Intel-based 7nm data centre CPU design in the first half of 2023."

Fun Facts:

“The Casio fx-83GT PLUS Calculator Problem”:

See the 12m18s YouTube video showing the strange calculation by the Casio Calculator.

You enter 11, press the power of 6 then divide by 13, that is 116/13. A pretty straight-forward calculation, you'd think.

Finally hit the equals button.

The answer you get is "156158413/3600 pi"! That's a large fraction multiplied by pi! What?

Here's proof:


Casio Calculator getting 11^6 / 13 wrong

Is this 116 / 13?

The actual value of 116 / 13 is

136273.­9230769230­7692307692­3076923076­9230769230­7692307692­3076923076­9230769230­7692307...

Casio's value is

136273.­9230769557­9586568248­6254966084­9514313201­3849436575­2919294527­1446159725­044189...

They agree up to

136273.9230769 which is 13-digits of accuracy. Not bad.

See the Casio Manual for the fx-82AU PLUS II and fx-100AU PLUS Scientific Calculators (similar to our fx-83GT PLUS Calculator) for more detail, including use of the S⇔D key, below.


The S⇔D key shows decimal or fractions

Is it just a user error using the S⇔D key?

If calculating the area of a circle, for example, you press Shift, then the 10x key. That gives you pi. Then hit multiply and then enter the radius and hit the Square button. This calculation will be pi × r2.

But the important thing is that the Calculator will display the answer as a multiple of pi.

Say the radius is 12, then the displayed answer will be 144pi. Then, pressing the S⇔D key will give the result in decimal.

Maybe that's what is happening in this YouTube video. The screen is just in the wrong mode.
